I have type 4 cv's. When I mount the tabs for the a arms to the frame should I make the pivot point (attachment point) of the a arms line up with the pivot point of the cv. And the same for the upright (Wheel)side also.
And where exactly is the pivot point of a cv. In the center of the outer race, if thats what it is called?
I hope this makes sence

How come every time I submit a post the sceen goes blank and I have to go back into catagory that I posted in to see it. ???

Check your settings on the CP...I get that when I post and get a PM at the same time

Could you please explain more on the "Maybe but not likely"
Does it matter if the axle is not centered between the two a arms, like on the barricuda, it is closer to the bottom a arm but parralel to both, or as long as the distance on the frame mounts is the same distance as the upright mounts.

If the same length arms are used top and bottom you would have no camber gain on suspension droop. You generally want camber gain. Problem is that the droop is reduced by the amount of degrees of camber gain. Usually approx 2-5 degrees. To accomplish that you need a shorter top arm. Arm mount points also influence suspension geometry changed. Many of us before we had CAD abilities just drew it out full size on the shop floor andphysically saw what happens.
-
So, camber gain is accomplished when the top of the tire leans in towards the buggy. Right :-[
-
No, that's just camber. Camber gain is when the tire leans in more at full bump than it did at full droop.

Camber gain is the amount it changes from ride height to full bump.
Getting this set-up correctly with A-arms can be kind of a pain. If the lower arm is below the centerline of the axle it needs to get longer. Sometimes this is hard to do with brake rotors and stuff getting in the way. Your best bet is to have to lower arm pivot at the same plane as your axle. Then you can dick around with the upper arm length to get the desired camber gain without getting to much in the way of plunge.......

yup
-
Yeah, I was in a hurry. Point was that the word "gain" tells ya there's some change going on.

I think it should have said the lower arm should be parallel to the axle,not in the same plane.. Thanks for pointing that out.
-
With the lower mounted up parallel with the axle the load on the upper arm will actually be less. It also gets your lower more ground clearance while still providing protection for the axle.

I hope this does't sound too stupid, but does'nt the lower a arm have to be below the centerline of the axle? ???
